Blind actuator 1-gang flush-mounted Order-No. 2165 00 - Gira

Software "Venetian blind, input 20BD11"
Functional description
i At the beginning of each ETS programming cycle, the device always executes a "stop"
command for the output.
i The "Behaviour after ETS programming" as configured will be executed after every ETS
application or parameter download. A simple download of the physical address alone or
partial programming of only the group addresses has the effect that this parameter is
disregarded and that the configured "Behaviour after bus or mains voltage return" will be
executed instead.
i After programming with the ETS, the safety functions, the forced positions and the sun
protection function are always deactivated.
Presetting the behaviour in case of bus voltage failure
The parameter "Behaviour in case of bus voltage failure" can be preset under "O1 - General".
The parameter defines the behaviour of the shutter output if only the bus voltage fails.
Depending on the selected operating mode, the ETS adapts the designations of the parameter
settings ("raising" ↔ "opening the louver" / "lowering" ↔ "closing the louver).
o Set the parameter to "stop".
In case of bus voltage failure, the device switches the relays of the output to the "stop"
position. A drive movement, if any, will be interrupted.
o Set the parameter to "no reaction".
In the event of bus voltage failure, the relay of the output shows no reaction. Movements
still in progress at the time of failure will still be completed as long as the mains voltage is
still on.
i As the device is supplied solely by the bus voltage, it is not ready for operation between a
bus failure and the setting of the appropriate reaction up to the bus voltage return.
i When there is a bus voltage failure, the current position data is permanently saved
internally, so that these position values can be accurately repositioned after bus voltage
return, should this be configured. The data is stored before the configured reaction for bus
voltage failures takes place and only if the bus voltage has been available before without
interruption for at least 20 seconds after the last reset (storage capacitors sufficiently
charged for storage purposes). The data will not be stored, if the position data is unknown.
The following rules apply for the position data to be stored:
The current blind, slat and louver positions are stored. With Venetian blinds, the height to
be stored is always referred to a slat position of 100 %(cf. "Calculating the slat position").
Positions temporarily approached will be stored also for those outputs that are involved in a
travel movement at the time of data storage. On account of the fact that position data is
stored as integer percentage values (0...100), a minor deviation from the positions reported
back later during bus voltage return (number range 0..255) cannot be avoided.
In case of ETS programming, the saved position data is not lost.
i In case of bus voltage failure, the current states of the forced position control or – if
configured – also the slat offsets of the sun protection positions are stored as well.
Setting the behaviour after bus voltage return
The parameter "Behaviour after bus voltage return" can be preset on parameter page
"O1 - General".
Depending on the selected operating mode, the ETS adapts the designations of the parameter
settings ("raising" ↔ "opening the louver" / "lowering" ↔ "closing the louver).
o Set the parameter to "stop".
In case of bus voltage return, the device switches the relays of the output to the "stop"
position. A drive movement, if any, will be interrupted.
o Set the parameter to "raising" or "opening the louver".
After bus voltage return, the device raises the blind or opens the venting louver.
